To all 'whom t may concern.'

Be it known that L Mnnvm tamrrrg-nr. a citizen of the United States, and resident of Lawrenceville in the county of Brunswick and State of firginia, have invented a eertain new and useful improvement in Meters', and do hereby declare that the following is a full, clear, and exact description thereof.

My invention is an improvement in meters, and. the invention has for its object to provide a meter for use with motor vehicles',

wherein. a supportingcasing is .provided in which is mounted a speedometer and a series of odometers, arranged 1n .series Wltn thnr axes parallel, the casing having a reading opening for each odometer, together with a sommen driving means for all oi the odometers for operating thc-fn in synchronised, and wherein each odometer is provided with means extending outside' of the easing fer permitting the particular odometer to be disconnected from the operating means and to be reset, and wherein adjacent to earh reading opening a legend iss-arranged, iden tifying the particular odometer within eertain essential operating elements of the ve-.

. hicile, and with. certain essential operations to be performed aboutv the vehicle.

In the drawings; Figure l is a tace View of the improved meter; F 2 is a section on the line 2-2 of Fig. 3; Fig. 3 is a section on the line 3-3 of Fig. 1, and Figa. isf

an enlarged detail View, paltiy in section, through the operating mechanism for 'the speedometer.

In the present embodiment o' the invention, a easing is provided consisting of a cup-shaped body 1, externally threaded at its upper end, and a cover plate 2, resting on the n per edge of the side wail of the body, an covered by a disk 3 of transparent material, as for instance, glass, the disk and the plate 2 being heid in place on the body by means of a bezel ring e which has the threaded engagement with the body.

A speedometer of ordinary construction is arranged within the body of the casing, near the bottom thereof, the particular con struction' of the speedometer forming no part of the present invention, and for that reason not shown, and the speedometer is;

Connected to an indicating hand 5, arranged on the 'upper surface of the plate 2, between the Same and the disk 3 oi' transparent inatw rial. The hand f nffindicator 5 is connected with the upper end of shaft 6, which is operated by the operating mechanism at y ranged Within the body.

.A number of odometers 7, fourteen in the present instance are mounted in the casing between the plate 2 and a partitionl niate 8, which is provided with a marginai iiange S) fitting the inner face of the body i of tne easing. and secured thereto by' means ,of screws 10 passing through the :flange and engaging the bod Each odometer consists of a series of nm" bei Wheeisrmonnted upon a shaft il, which is journaled at its inner end in oneot the arms l2 of a substantialiy loi-shaped bracket, consisting of the said and a body 13. The bracket is arranged diainetrieaily of the easing, and secured to the side wailof the body by ineans of' serews i4, which are passed through the body and through anga lar lugs i5 at the yends of the arms remote from the body. Thus the arms vl2 of the body are heid parallel with each other, and with a diameter of the casing.' i

At their outer ends the Vshafts extend through the side wall er", the casing, and are journaied in bearings iti oonneeted with the side wali and extending on. opposite sides of the same, and with aresetting of the casing.. y i

The shafts li are connected 'to the number n P in any usual or desired manner, and in such manner that by turning the shaft the said wheels may be dis-1 eonnecte'l from the `shaft and may be reset at aero bymeans of the shaft.

each shaft li 'is provided 'se l A worin wheel 18 is secured to the innerl und of ear'h shaft, between the series of nnmher wheels and the adjacent arm 12 of the lwacket7 and each worm wheel meshes with a worm i9 on a worm shaft 20, extending paealiel with the adjacent arm 12 ofthe bracket below the same.

[Cach Worm shaft is provided with a bevel gear 2l' intermediate its ends, and each of nii teeth of a gear Wheel 31, which is keyed to a stub shaft 32, mounted in a bearing plate 83 secured Within the casing, and a' collar 34 is 'adjustably held on the stub' shaft above the bearing plate by means of a set screw'35.

The gear wheel 31 meshes with a gear Wheel 36 on the shaft 27 before mentioned, and with a second gear Wheel 37 on a second stub shaft 38 jonrnaled diametrically opposite the shaft 32 in a bearing plate 33 arranged in the same manner as the plate 33.

The gear wheel 37 is keyed to the shaft below the bearing plate. and a second gear wheel 39 is keyedto the shaft above the bear: ing plate. This `gear Wheei 39, which is of larger size than the gear Wheel 37, meshes with a similar gear Wheel 40, on the shaft 27 above the gear Wheel 36.

A gear wheel 4i is mounted on the shaft above the gear Wheel 40 and is rigid therewith, the said gear Wheel 41 beingr of larger size than the gear Wheel 40. The gear wheel 41 meshes with a pinion 42 jonrnaled on another stub shaft 43, which is jonrnaled be tween the stub shaft 38 and-the shaft 27, and is provided with a gear wheel 44 above the pinion, and rigid therewith, which meshes with a gear Wheei 45 keyed to the stub shaft 46, which supports the bevel gear 26, the said stub shaft being journaled in the partition 8 and in alinement with the shaft 27 before mentioned.

The gear Wheels 31, 36, 37, 39, 40, 41, 42, 44 and 45 consti-tute a speed changing gear, for driving lthe odometers at a proper rela tive speed with respect to the movement of the front Wheel ot the vehicle, and it will be evident lthat when the crown gear. 29 is driven, the bevel gear 26 will be driven at a greatiy reduced speed and vvill drivel the Worm shafts 19, which in turn drive the odometers in synchronism.

The plate 2 before mentioned is provided i with. a slot or opening 47 at each odometer for permitting the odometer to be read, and the said plate is also provided with a legend or label 48 adjacent to each opening and above the same.

In 'the present instance fourteen odometers are shown, but in practice there will be sixteen odometers six odometers identified with the tires, fonr with the tires in use and two with the tvvo extra tires, `tivo odometers "with the oil and fuel supply, tivo with the packing of the differential and transmission. and two with tne trip and total mileage, and

the other four with certain necessary opera tions to be performed about the vehicle .at predetermined mile-ages, as for instance, oiling vor greasing the different parts, refilling the radiator and the like. A

The legends adjacent to the odome-ters are identifying labels indicating the purpose of the odometersc The 'speedometer indicator 5 coperates with ascale 49, arranged on the plat-e 2, at 'the lower side thereof,for indicating the speed attained bythe vehicle.

In operation, the speedometer and the 'odometers or indicating devices are driven in synchronisni from the shaft 30,\\ and the indicator 5 wlll indicate the speed attained by the vehicle. When a new tire is placed vthe odometer pertaining to rthat particular tire is reset to zero, and it will be evident that the said odometer will give the mileage made by the said tire. When the tire is removed temporarily, the odometer pertaining thereto is disconnected from the shaft 30, and is permitted to remain idle until the tire is replaced.

If an extra tire is substituted for the tire removed the odometer pertaining to the extra tire wiii be connected with the driving shaft and the said odometer will record thev mileage made by the extra tire.

As regards the four odometers devoted to signaling or indicating the necessity for performing certain operations, these odom leters may if desired be provided with the indicating or signal shutters shown and described in my co-pendirxg application, Serial No2 58,808, filed October 30, 1915.

There are certain important practiced results from the arrangement of the odometers in tvvo series along side of each other. If the fourteen odometers shown in the drawings were arranged inv a single series, the instrument would be a' long` narrow affair, its length being something like twelve inches, a length that would be prohibitive of its use on an instrument board 'of an automobile; and moreover the single driving shaft would be something like twelve inches long, and as of necessity, it must be slender, trouble would arise in properly driving the series of odometers from it because of the effects of the torsional strains. Again, a long series of sight openings would be in convenient and annoying to read, By my twoseries arrangement,the length of the instrument can be one-half and the attractive looking circular form of casing may be employed, which, of course, would be out of the question with the long single series, and subdivision of the sight openings into tivo groups renders the picking out of any-particular sight opening to read the registration thereat easy, since the eyes do not have to run over the `great length of a long series. Instead ,of one YShaft to drive all. the odometers, there may be a comparatively, short shaft for* auch uf h@ two series receiving lmziuil from a conmwn dving mehanism which can bij made 0i* the necessary Wsight and strength withou' objectionable results. her mvmitags which Wii bf: pelceive by those skilled in the awt come from my twfmfseries arrangement, but I have mem tioued @mug-gh to show its great, utiity and mvantnge l.
